Chromecast to Get a “Power-save Mode”?

Let me start by saying this, I have only very, very limited information on this. I am basically sharing a commit log that I found today. However, the text on this commit log is pretty straightforward. That is the reason why I decided I should share it.

The Code

After no streams have been playing out audio for a few seconds, trigger power-save mode. Note that paused streams do not count as playing out for this purpose.

The bug associated with this change is private. That closes a door for additional information. I am also concerned about the “Audio” part. Is this only a part of a set of code changes for Chromecast and Chromecast Audio?

I usually end posts about upcoming Chrome OS features saying that the feature will be available in few weeks. I cannot say anything like that with Chromecast. When was the last time we heard about a new Chromecast feature?

So, what do you think? Is this really an upcoming Chromecast feature, or am I just seeing things?
